COMBINATION CLIPER AND DIVIDER Filed Feb. 4, 1928 WITNESS: ATTORNEY Patented Mar. 11, 1930 UNITED STATES PATENT OFFICE COMBINATION CALIPER AND DIVIDER Application filed February 4, 1928. Serial No. 251,940.

This invention relates to improvements in tools, an object being to provide a single tool which may be used as a rule, a rightangle square, a bevel square, a compass, an outside 5 caliper, and an inside caliper, so that the tool may replace all of the tools ordinarily necessary to perform the functions of the instruments or tools above mentioned.

Another object of the invention is the provision of a tool of the above character which may be folded and used as a rule without unfolding, the construction providing a smooth graduated edge for the tool which may be placed in contact with an article being meas- 15 ured.

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claim.

In the drawings j Figure 1 is a plan View of a tool constructed in accordance with the invention and shown in folded position.

Figure 2 is a smiliar view with the tool open.

Figure Sis aview illustrating the use of the tool as a compass.

Figure 4 is an edge view of the tool.

Figure 5 shows the use of the tool as an outside caliper.

Figure 6 shows the use of the tool as an inside caliper.

Referring to the drawings in detail wherein like characters of reference denote corresponding parts, the tool as shown comprises a pair of legs 10 and 11. These legs are pivotally connected together by means of a bolt 12 so that they may be relatively adjusted, and are held in adjusted position by means of a thumb nut 13. The legs 10 and 11 taper from their pivotally connected end to their free ends, so that the latter are pointed which permits of the use of the tool as a compass, as illustrated in Figure 3 of the drawings. One or both legs of the tool may be graduated int-o inches and fractions thereof, so that the.

tool may be used as a rule. The graduations are arranged at a right angle with respect to the edge 14 of the arm 10 and when the edge 15 of the arm 11 is adjusted in line with the mark or graduation 16, these edges 14 and 15 will form a right angle as shown in Figure 2 of the drawings. This ligure also illustrates by dotted lines the use of the tool as a bevel square.

One edge of each arm of the tool is inset for a relatively short distance from its outer or pointed end as shown at 17, and extending from this inset edge is a lug 18. rlChe outer extremity of this lug is arranged in a plane with the major portion of the edge of the arm, so that when the tool is closed or folded as shown in Figure 1 of the drawings, the edges of the arms will be flush and there will be no projecting portions to interfere with placing the graduated edge firmly against an object being measured.

The lugs 18 permit of the use of the tool as an outside caliper as shown in Figure 5 of the drawings, or the tool may be arranged so as to reverse the position of the lugs 18 and permit of the tool being used as an inside caliper.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claim.

Having described the invention what is. claimed is A tool comprising a pair of arms pivotally connected at one end and tapering from their pivoted to their free ends, one edge of each arm being inset for a relatively short distance inward at its free end and providing straight edges disposed in a plane substantially parallel to the adjacent edge of the arms with the inset portions of the arms being oppositely arranged, and a lug extending from the intermediate portion of the inset edge of each arm with the outer extremity of the lug in the plane of the major portion of the edge of the arm.

In testimony whereof I affix my signature.
